Ghost Writer on Hint of Blue

#bcb7ad on #cee1f2

Body text at this size

And the smaller size most interfaces actually use for paragraphs — the size that decides whether a pair is usable.

Caption text, which almost nothing passes.

WCAG 2.1

1.49:1

Fails AA

Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.

APCA

Lc 19.6

Clears Lc 15 — disabled or purely decorative text, which is not meant to be read.

Dark text on a lighter ground.

Colour difference

ΔE00 17.6

different colours

Above 10 — related only in the sense that both are colours.

What the text colour has to become

#676259 is the nearest colour of the same hue that passes AA on #cee1f2, at 4.50:1. Only the lightness moved — which is the point: your colour stays recognisably your colour.

And to someone missing a cone

protanopia

Body text

Ratio 1.53:1, ΔE00 17.4.

deuteranopia

Body text

Ratio 1.47:1, ΔE00 18.5.

tritanopia

Body text

Ratio 1.44:1, ΔE00 30.3.

The weakest of the three is protanopia, where the two are ΔE00 17.4 apart against 17.6 for a trichromat — still clearly two colours.
